Abstract First record of Tricyphona (Tricyphona) contraria Bergroth, 1888 (Diptera: Pediciidae) from the Iberian Peninsula and other inter- esting records of Tipuloidea from caves of Catalonia (Spain) Tricyphona (Tricyphona) contraria Bergroth, 1888 is registered for the first time in the Iberian Peninsula, as a result of a biospeleologi- cal survey conducted in a cave of the emblematic Montserrat massif located a few kilometers from Barcelona city. Also, we offer a new distribution data for Rhypholophus haemorrhoidalis (Zetterstedt, 1838), Elliptera hungarica Madarassy, 1881, Dicranota (Paradicranota) subtilis Loew, 1871, Tipula (Lunatipula) albostriata Strobl, 1909 and y T. (Mediotipula) cataloniensis Theowald, 1978. This is as a result of a partial revision of the Tipuloidea collection housed in the Museum of Natural Sciences of Barcelona, especially of those specimens col- lected in cave environments, which represents the confirmation of these species in Spain. Key words: Diptera, Tipulidae, Limoniidae, troglofauna, cave dwellers, biospeleology, Iberian Peninsula. Resum Primera cita de Tricyphona (Tricyphona) contraria Bergroth, 1888 (Diptera: Pediciidae) per a la península Ibèrica i altres registres interessants de Tipuloidea capturats en coves de Catalunya (Espanya) Tricyphona (Tricyphona) contraria Bergroth, 1888 es registra per primera vegada a la península Ibèrica, com a resultat d’una prospecció bioespeleológica realitzada en una cova de l’emblemàtic massís de Montserrat, a escassos quilòmetres de la ciutat de Barcelona. També, com a resultat d’una parcial revisió de la coŀlecció de Tipuloidea allotjada en el Museu de Ciències Naturals de Barcelona, en particular d’espècimens capturats en coves, s’ofereixen noves dades de distribució de Rhypholophus haemorrhoidalis (Zetterstedt, 1838), Elliptera hungarica Madarassy, 1881, Dicranota (Paradicranota) subtilis Loew, 1871, Tipula (Lunatipula) albostriata Strobl, 1909 i T.

Pilbara thysanurans are poorly known and the taxonomy of Nicoletiidae is based on their DNA sequences rather than published species descriptions. Subterranean Atelurinae are well known throughout the Pilbara; however, nearly all of the species recognised to date appear to be range restricted.

Subterranean Biology 13: 17–34. doi: 10.3897/subtbiol.13.6991 Abstract Most sampling of troglofauna occurs in caves but troglofauna species are widespread across the vadose zone in Western Australia in iron ore deposits and calcretes. Other than in karstic calcrete, the subter- ranean spaces in the Western Australian vadose zone are small and often of similar size to the troglofauna inhabiting them. Here we describe how troglofauna can be sampled in the vadose zone using a technique called scraping, in which a haul net is dropped down a hole drilled for geological exploration. We analysed of the results of 10,895 sampling events in which both the scraping and trapping techniques were used. In the Pilbara region of Western Australia, where most of the fieldwork occurred, scraping collected approxi- mately three-quarters more troglofaunal animals than trapping and more than twice as many troglofauna species per sample.

    KARST WETLANDS BIODIVERSITY ANI) CONTINUITY THROUGH MAJOR CLIMATIC CHANGE: AN EXAMPLE FROM ARID TROPICAL WESTERN AUSTRALIA W.F.Humphreys krrestrial InvertebrateZoology, Museum o.f l,{atural Science, WesternAustralian Museum, Francis Street,Perth, WA6000, Australia; E-mail: [email protected]. gov. au Abstract Subterraneankarst wetlands,recently included as a wetland type under the Ramsarclassification, are introducedhere to the wetlandsbiodiversity literature.The generalcharacteristics of karst land- scapesexplain the connectionswith non-karsticwetlands, the often diffuse limits to karst wetlands and their vulnerability to exploitation and pollution. Less than l0oA of the Earth shows distinctive karst landforms but on a global basiskarst wetlandssupport the greaterpart of subterraneanbiodi- versity.This introduction is amplified by a detailed account of a single karst wetland Cape Range peninsula,Western Australia. Cape Range,the only orogenicTertiary limestone in Australia, occurs on a continent relatively devoid of karst. It lies in the arid tropics where surface water flows are mostly episodic and fre- quently saline. The Cape Range karst wetlands contain both freshwater and anchialine wetlands whose natural accessis through a few karst windows and caves.The anchialine system shows marked stratification of their physico-chemicaland biological profiles. The lack of surfacewaters and the particular geographical context means that much of the groundwater fauna represents ancient geographical or phyletic relicts. A general case is made supporting the persistenceof groundwaterfauna in karstic systemsthrough geologicaleras. Introduction The 6th Conferenceof ContractingParties to the RamsarConventionl (Brisbane 1996) voted to include subterraneankarst wetlandsas a wetland type under the Ramsarclassification system. This inclusionhas far reachingimplications, not only for karst regions,but also for a wide rangeof wetlands,and for groundwatercon- servationgenerally.

  • A Review of Subterranean Fauna Assessment in Western Australia
    Office of the Environmental Protection Authority A review of subterranean fauna assessment in Western Australia DISCUSSION PAPER February 2012 A review of subterranean fauna assessment in Western Australia Acknowledgment: Cover photo Paradraculoides bythius courtesy of the WA Museum. Recommended citation: EPA (2012) A review of subterranean fauna assessment in Western Australia. Environmental Protection Authority, Perth. 2 A review of subterranean fauna assessment in Western Australia EPA Chairman’s foreword The Environmental Protection Authority (EPA) has legislative responsibility to protect the environment and to prevent, control and abate pollution and environmental harm. It fulfils these duties in part by conducting environmental impact assessment (EIA) of major projects and providing advice to Government on whether the environmental risks and impacts can be managed. While the EPA has been conducting assessments for four decades, it is only in the last 17 years that subterranean fauna has become prominent as a key environmental factor in around 40 major project assessments. Questions have been raised about: • the legal and policy drivers behind EPA consideration of subterranean fauna; • the changing state of knowledge of subterranean fauna in WA; • what has been learned through EIA practice since subterranean fauna was first identified as an environmental factor; • the effectiveness of current assessment practices in meeting the EPA’s objectives; • opportunities to move towards a risk-based approach in considering subterranean fauna; and • potential alternative assessment procedures. In 2011, the EPA resolved to pursue a more risk-based approach to environmental impact assessment of subterranean fauna related issues. The need for and possible approaches to such a change are laid out in this discussion paper.
